What to do if your clutch master cylinder is leaking?
If you can find no trace of a leak, fitting a complete service kit to both cylinders may cure the trouble. If the fluid level is normal but the clutch ‘drags’ (will not disengage properly), and particularly if the pedal feels spongy, there is air in the system.
What causes a clutch slave cylinder to leak?
The main chamber seal in the middle of the clutch slave cylinder will split and leak out brake fluid causing the reservoir in the clutch master cylinder to become low. As the pedal is pushed down, the plunger inside the cylinder housing will cause brake fluid to spray out at a strong force past the seal.
When to replace dust boot on clutch master?
Failing dust boot needs to be replaced as soon as possible. If no damage has been done to the surface of the cylinder bore and the plunger is in a good condition, rebuilding the MC is a relatively simple procedure. Rebuild kits are readily available.
Where is the clutch master located on a car?
The clutch master cylinder is usually found on the bulkhead next to the brake cylinder. Usually each cylinder is directly in front of its pedal, so the clutch cylinder is the one on the right as you look from the front of the car.
How does the clutch work on a Saab?
Expanding point 1: That’s just the way it is. Saab clutches just aren’t like your average car. You can foot-pump the clutch on most cars and the pedal will return on its own; on the Saab, if you push the un-bled pedal to the floor, it just stays there, and pressure never builds.
Where can I buy a cap for a Saab master cylinder?
The best bet would be to buy a stock cap for the master cylinder (Saab PN 89 66 152), or get one from a junk yard. Once you have a cap that can be made to seal, you can buy a tire valve stem at an auto parts store and drill a hole in the cap to accept the valve stem (I believe it takes a 1/2″ hole).
How to repair clutch master cylinder leak or failure?
Using grease will help the plunger seal to go into the cylinder smoothly. Smear the pushrod and retaining washer with red rubber grease. Pack the dust boot with red rubber grease, as well. Now, you are ready to assemble the master cylinder. Push the plunger into the bore, insert the pushrod with retaining washer and secure them with a snap ring.
